Just for context, this technology is not made for any specific end-consumer. This is for backbone connections of ISP and higher tier networks.

In that space, 400Gb/s is the current stuff that's being rolled out with 800Gb/s starting to get traction. 1.2Tb is just the next step to reduce the amount of Fibers and Ports used per connection (renting fibers of an undersea cable is expensive).

Though one issue I see slowing adoption is that new fibers are needed. With coherent optics we already achieve 800G with the same single mode fibers already in use.
